" vIIininLIGfH'nA rApplicationfiled February 21, 1923.yServia1iNQn620468f "f i Be it known that I, WILLIAM H. RAPP, a

. citizen of the. United States, and a resident of Philadelphia,Pennsylvania,` have invented certainl new and useful Improvements in qHeadlifrhts -for Automobiles and theflike,

of which thefollowing is a` specification.

i My invention relates to that type of head? light inwhich thedampffori'ningthe source of illumination is-l at all times concealed 'u'from View, thereby eliminating the` fblinding effect incident to'exposure of. a :brilliant lighting medium Within the range of vision ofpersons approachingthe headlight, v

-The main object' ofniy invention is to provide a cheap andeiiicient'means kfor car- 4be' projected4 forward'at a slightly provideya. lightvsupporting structure that will -providea suitable source ofillumina- .tionV 'and'by means of. which the rays of light emanatingfrom the-electric lamp will own- Ward inclination and serveto lighttheroad i in front of-the automobilejinstead of being diffused in alldirections. l s

*AI further object of my inventionis toprovide a combined fshield andelectric lamp-carrying element of a single integral member and of"simple construction, attachable to any of the common or Vstandard formsof headlightstructures. j

These and other features of my invention y are more vfully describedhereinafter, reference being hadstolthe accompanyingdrawings, in whichV- `Figure 1, is a sectionalielevation of an ordinary automobile lamp ofthe headlight type to which .my/,improvedshield land lamp-carryingattachment may be applied, taken .onl the line l-fLvFig. 2.' n

desired projection of the This bent-up portion 15 is adjustable as toits angle, -so that the light reflected thereby onto the surface of themain reflector 2 may be at the proper angle to insure the illuminationthrough the unobstructed lower portion of the front glass or lens 4 ofthe lamp structure. If desired, or it is necessary to insure Y supportfor this bent-up portion 15, av strap or straps) l18 may'extend betweensame and the shield. While this feature is shown in connection with theform of `structure illustrated in Fig. 4, it will be understood that itis also applicable to the structure shown in l Figs. 1, 2 and 3.

In the structure illustrated in Figs. 1, 2, 3 and 4, I have shown thelamp-carrying ortion 15, as projecting upwardly from the oweredge of theshield 10. It is obvious,

i of course, that this arrangement could be reversed, and in Fig. 5, Ihave shown a shield structure having a lamp-carrying portion dependingfrom the upper edge of the plate portion 10. Centrally or substantiallycentrally disposed with respect to the upper curved edge of the shieldplate is a rearwardly extending portion 12a, which may be secured to thelamp casing or the reflector by a fastening 13a, forwhich purpose aportion of its wall may be struck-up, Vas indicated in the drawing. Theportion 12a may be integral with the shield 10, and may follow thecontour of the reflector 2, or casing 1', and be directly securedthereto, instead of striking up the portion illustrated in Fig. 5. Thisportion 12a is bent to form a depending part 12b, disposed at a suitableangle with respect to the shield, in substantially the same manner asthe portion 15, illustrated inFigs. 1, 2, et seq., and which may alsoconstitute a reflector. The surface of the depending part 12b may be ina single plane, or it may be slightly concave, so as to v collect therays of light emanating from a lamp 17a, forming the source ofillumination, and mounted in a socket 16a, carried by the portion 12".If it is necessary to hold the part 12b against vibration, it may extendto and be connected to the shield, or a securing strap 18a may beemployed.

It will be observed that the source of illumination is disposedwhollyabove the lower edge of the shield plate, and that the angle ofthe reflecting element 15, or 12b, may besuch as to properly direct therays -of light toward the surface of the reflector 2, and insure theproper reflection through the lens or front glass 4 of the headlight.The rear of the casing 1 may carry a suitable insulating sleeve 2O f-orthe passage of the current conducting cord 21, and this cord may lie onthe inside ofthe casing or between the casing and reflector, and pass tothe socket carried by the supporting portion 15, or 12b, for theelectric lamp, around the edge of the shield.

The shield is made of relatively heavy sheet metal, which metal may havea highly polished surface, giving a pleasing aspect at the fr-ont of thelamp, and also furnishing the desired reflecting surface.

While I have shown and described the combination shield and lamp supportas being carried by the reflector or the casing, it is obvious that itmay be attached to the door frame, if the latter is arranged to swing onhinges,fwith provision -for suicient slack in the current conductingcord yto insure proper operation of the same.

As may be understood from the foregoing description, the combinedshield-and lamp support may be detachably secured to any headlightstructure by properly fastening the inturned portio-ns -or side wings ofthe plate 10 to the lamp casing, or the reliector. For lamps as nowconstructed, with parabolic or semi-circular reflectors adapted toreceive an electric lamp in the centre, the aperture for the-lamp socketmay receive an insulating sleeve 20', to serve 'as the channel for thepassage of the-current conducting cord to a lamp carried by my improvedsuplll() port and shield. With the type of lamp structure just referredto, any ordinary reflector, of semi-circular or other shape, may beemployed in the headlight casing; `being secured therein in any suitablemanner independently of the shield and the lamp support.

While I have described' my improved shield andlight-support as made ofsheet lamp supporting portion having a light refleeting surface, and alight source mounted.

in said light reflecting surface and facing rearwardly thereof.

2. In combination with a headlight casing, the usual concave reflector,and glass closure, a light projecting and shielding device comprising asubstantially semi-circular lplate having integral wings thereon forattachment to the headlight casing, an angularly disposed lampsupporting member in the rear of and integral with saidl plate; saidlamp supporting portion having a substantially concave surface acting asa light refleeting surface, and a light source mounted in said concavesurface and facing rearwardly thereof."

3. In combination with a head light casing, the usual concave reflector,and glass closure,

plate having integral wings thereon for attachment to the headlightcasing, an angularly disposed lamp supporting member in the rear of andintegral with said plate and projecting upwardly from the lower 'edge 25source mounted in said light reflecting surface and facing rearwardlythereof.

In witness whereof I have signed this 30 specification.
